Child Survival Studies
The Alliance is supporting three clean cooking and child survival studies to
better understand the potential impacts of clean cookstoves and fuels on birth
outcomes and child survival. These are the first studies in which truly clean
technologies are being evaluated, and they will provide important information
in estimating the magnitude of health impacts that can be attributed to higher
PM reductions due to clean cookstove and fuel intervention programs.

KEY FACTS
•
Acute lower respiratory infections (ALRI) are a leading cause of death among children under 5 in the world
•
Very few data exist to estimate the dose-response function for ALRI in low-income countries. As a result,
it is unclear how “clean” cookstoves need to be in order to see important reductions in risk of ALRI.
•
Current data show that cooking with biomass causes a 90g decrease in birthweight; however, there is no
data on cooking with clean fuels and how this will affect birth outcomes.
•
Although many “improved” biomass stoves reduce indoor PM concentrations by as much as 50 – 70%,
indoor concentrations remain much higher than current WHO indoor air quality guidelines.
STUDY DETAILS
GHANA:
The Ghana Randomized Air Pollution and Health Study (GRAPHS) is evaluating the impact of adopting
clean cooking (biolite stoves or LPG) during pregnancy on birth weight and childhood pneumonia. This study seeks to determine the respiratory pathogens responsible for pneumonia infections in a sample
of physician diagnosed severe pneumonia cases. This will shed important new light on which respiratory
pathogens are most responsive to household energy interventions.
NEPAL:
The Nepal Cookstove Replacement Trial is a large, cluster-randomized, step-wedge designed trial to assess
the impact of replacing traditional open burning biomass stoves with an “improved” stove or LPG on the
incidence of ALRI and adverse reproductive outcomes in a rural population in southern Nepal.
NIGERIA:
The Nigeria study is a randomized controlled trial to assess the impact of replacing either traditional
biomass stoves or kerosene with ethanol on birth outcomes. This study occurs in an urban population
where the majority of women use kerosene as their primary cooking fuel. Because this study will have data
from open burning, kerosene, and ethanol, it will have the ability to establish a dose-response relationship
between measured pollutants (PM and CO) and birth outcomes.
